They are given the solution that inductance is proportional to the square of the number of turns. So the number of turns given 200, square of 200 equals to 40000, in option 4 is contain 40 mH. So option D is correct. I hope you all understand.

L = 4*pi*10-7*N2*A/l.
So, L is directly proportional to square of the turns i.e N.
